Bug ID 1499
Summary Intel uncore power library fails because of too many frequenc= ies
Product DPDK
Version 24.07
Hardware x86
OS Linux
Status UNCONFIRMED
Severity normal
Priority Normal
Component core
Assignee dev@dpdk.org
Reporter stephen@networkplumber.org
Target Milestone --- 

Running 24.07-rc2 on Intel core bo=
x fails the power uncore test because:

RTE>>power_intel_uncore_autotest
POWER: Too many available uncore frequencies: 33
POWER: Cannot get available uncore frequencies of pkg 00 die 00
Cannot initialise uncore power management for pkg 0 die 0, this may occur if
environment is not configured correctly(APCI cpufreq) or operating in anoth=
er
valid Power management environment


The CPU is: 11th Gen Intel(R) Core(TM) i7-1165G7 @ 2.80GHz
initial_max_freq_khz:3600000
initial_min_freq_khz:400000
max_freq_khz:3600000
min_freq_khz:400000

Which leads to this expression:
        num_uncore_freqs =3D (ui->init_max_freq - ui->init_min_freq) =
/ BUS_FREQ +
1;
        if (num_uncore_freqs >=3D MAX_UNCORE_FREQS) {
                POWER_LOG(ERR, "Too many available uncore frequencies:=
 %d",
                                num_uncore_freqs);

I.e:
        num_uncore_freqs =3D (3600000 - 400000) / 100000 + 1
                         =3D 33

Looks like an off-by-one error, was this ever tested?
